- Step 3: Chill the brownies until firm, then cut them into rectangles or squares to form the ‘heads’ of Frankenstein’s Monster.
- Step 4: Mix green food coloring into the chocolate frosting until you reach a bright green color, then spread a thin layer of this frosting on top of each brownie.

Tips & Variations

FAQs
Can I use homemade brownies instead of boxed mix?
Yes, homemade brownies work just as well and allow you to control the ingredients and texture. Just ensure they are firm and well cooled before decorating.
How do I prevent the frosting from melting or sliding off?
Make sure the brownies are completely cooled and preferably chilled before spreading frosting. This helps the frosting set quickly and hold decorations in place.
